Silly String is a popular aerosol novelty product that sprays a continuous stream of colorful, foamy plastic material, often used for entertainment purposes at parties, celebrations, and practical jokes. While it may seem like a simple toy, its chemical composition and applications are more complex than they appear. The product works by ejecting a liquid mixture under pressure, which rapidly solidifies into string-like filaments upon contact with air.
Wow, I loved these balls. I remember that they surpassed any other ball I ever owned for how high it would bounce. Even a golf ball, off the concrete, could not match. I used to throw the super ball off the house and field it with my baseball glove. It was incredible but after a few hundred times off the bricks, it would disintegrate, unlike the rubber baseballs, tennis balls, or golf balls I also used. They were made of a synthetic rubber invented by chemist Norman Stingley in 1964.
